Hibernating

Hi all, 

At the moment I feel like most of what I seem to do with my weekends is sleep or be shut down. Getting frustrated at not being able to have the energy to do all the projects I want to do. 

Is it a normal autistic thing to go through weeks of excessive sleeping?  Either as part of a cycle or just a normal thing. 

Any kind of insight would be great. 

Thanks,

Craig
